Quad, ITB and Lower Back Stiffness

Hi,

I’ve been stuck with an injury now for TWO Years and have tried everything and about five physios to fix it.

When running two years ago my right leg and lower back became completely stiff. Since then I haven’t been able to walk (let alone run!!) or stand for longer than ten to fifteen minutes without a very stiff quad, ITB, lower back, and hip abductors.

I have had scans and both they and my symptoms seem to rule out sciatica.
It seems I have extremely weak right glutes (both medius and max) which are constantly overpowered by my Quads and ITB (the result of a leg break ten years previous, and I have orthotics to treat leg length diffrence etc). I have tried all the usual exercises but whenever I try and do them (eg clams, Single leg push up in a prone position) my qauds take over and I can’t seem to get any strength imporvement from my glutes.

HELP! Does anyone know how I can calm down the overactive quads/hip adductors or any tips on technique for targeting the glutes??
